[0031] As Figure 5 shown, the utility model provides a kind of clamping device for metal welding, adjusting mechanism 38 includes knob 381, knob 381 movably connected on the left side of sliding clamp plate 36, the right side of knob 381 is fixedly connected with third screw 382, the inside of sliding clamp plate 36 is equipped with sliding recess, the right end of third screw 382 is penetrated to the inside of sliding recess and the outer surface is threadedly connected with threaded slide plate 383, the outer surface of threaded slide plate 383 is slidably connected with the inner surface of sliding recess, the outer surface rear sides of threaded slide plate 383 are all fixedly connected with sliding column 384, the inner surface front and rear sides of sliding recess are all slidably connected with lifting slide plate 385, the top end of lifting slide plate 385 is penetrated to the side of rubber pad 39 away from sliding clamp plate 36, the inside of lifting slide plate 385 is equipped with front and rear penetrating inclined slide groove 386, the outer surface of sliding column 384 is slidably connected with the inner surface of inclined slide groove 386;

[0033] The working principle of this metal welding clamping device will be explained in detail below.
[0034] like Figures 1-5 As shown, firstly, based on the position and spacing requirements of the workpiece to be welded, the dual-head motor 13 is started. The left and right output shafts of the motor drive the first screw 14 to rotate synchronously, and the threaded slider 15 moves left and right accordingly, thereby driving the connecting slide plate 16 to move, thus adjusting the horizontal position of the vertical adjustment bracket 2 to meet the welding requirements of the horizontal spacing between the two clamping arms 3. Next, according to the workpiece height, the adjustment motor 24 is started, and its output shaft drives the second screw 25 to rotate. At the same time, the threaded sleeve 33 is threadedly connected to the second screw 25, so the threaded sleeve 33 drives the sliding seat 31 to move up and down linearly along the sliding groove 23 of the dovetail plate 22, realizing the precise adjustment of the vertical height of the clamping arms 3, laying the foundation for diversified welding processes. After that, the workpiece is placed between the two clamping arms 3, and the motor is started. The clamping motor 34, with its output shaft driving the bidirectional screw 35 to rotate, causes the upper and lower sliding clamping plates 36 to move towards or away from each other along the bidirectional screw 35, thus clamping and releasing the workpiece. The rubber pads 39 on the opposite surfaces of the sliding clamping plates 36 increase friction and improve the clamping effect. Finally, for workpieces of different shapes, if it is a square workpiece, it is directly clamped and fixed by the sliding clamping plates 36 and the rubber pads 39. If it is a round workpiece, the knob 381 is turned, driving the third screw 382 to rotate, causing the threaded slide plate 383 to move left and right in the sliding groove. The sliding column 384 on the slide plate moves accordingly, and through the sliding connection with the inclined slide groove 386 in the lifting slide plate 385, the lifting slide plate 385 slides up and down and extends out from the sliding clamping plate 36, completing the clamping and fixing of the round workpiece. Throughout the welding process, the positions of each part of the structure can be readjusted at any time according to the welding process requirements to achieve different welding methods.
[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art.
